The designation came after the dog attacked and killed a shih tzu-bichon frise mix named Snoopy in Winnipeg's Linden Woods neighborhood. The dog also attacked Snoopy's owner.

Carolina Fridman said she was walking Snoopy, her five-year-old bichon frise-shih tzu cross, in Linden Woods when a Labrador retriever ran up from behind them and grabbed the 12-pound dog in its jaws.
